No. Wifi seems to be everywhere, well, anywhere we stay. We kind of base ourselves at my Wife's Mums place, then travel around from there, so no issues with that. The Great firewall blocks access to a lot of sites, FB, Flickr and lots of others, I'm quite happy not being connected to social media all the time. I don't really bother uploading images when travelling, I just take a few SD cards and use them like 35mm film. Sometimes I've not even bothered with any sort of computer device, just taken my phone. I went to NZ over Christmas/New year just gone, and I took my Intel Skull Canyon i7 NUC plus a 15.6" portable USB-C monitor. That worked pretty well, the USB-C monitor needs no power, it has cr@ppy in-built speakers so all you need is a single power point, a small Bluetooth keyboard/touchpad and you're away. Not really any bigger than a laptop, but a lot more useful. To me. Trip before that, just my phone. I did buy a local SIM card both times there, my Daughter and Son in law were also travelling at the same time, so made it easy to keep in touch and hook up here and there. This time I think I might take my tiny little Ryzen 7 7735 8 core 16 thread NUC, which is actually my main computer. I've got 4 TB of internal SSD storage in it, and another 1TB SSD in a very small enclosure. I'll be interested to see if I can access my NAS this trip, but not in the slightest bit concerned if I can't, between the SD cards and external storage I reckon I've got enough room for a couple of years shooting. Not months lol.
My phone is USB-C, it has removable micro SD cards, so that's another option, as I've also got a USB-C card reader that works a treat with it. We'll see
